Fein multi master, that's the good one, there is a knock off company trying to cash in on Fein, i think it might be Rockwell, but am not positive. anyways, i have the Fein and absolutely love it!! i work construction and have used the imitators that were owned by other workers, and all were junk! almost all of the guys have said,"next time i'm getting the Fein"!!! so, save yourself some money, buy the Fein the first time, buy it once, have it for life!!
good luck, hope this helps, car dude.
